About this study

Official title: The Effects of Pericardiotomy on Diastolic Reserve in Humans

The researchers are doing this study to find out whether there will be less increase in cardiac filling pressure after the surgeon opens the pericardium (the membrane around the heart) than when the pericardium is intact. The researchers want to see whether opening the pericardium is an effective way to reduce the blood filling pressures in the heart.

Read the detailed description

This study will enroll patients with risk factors for LV diastolic dysfunction, either coronary artery disease or aortic stenosis, who are already undergoing cardiac surgery for clinical purposes (e.g. coronary artery bypass grafting or valvular heart disease).

Hemodynamic tests will be performed using standard clinical resources used as part of routine care in this setting, including pulmonary artery (PA) catheterization. After obtaining written informed consent, patients will undergo induction with general anesthesia as per clinical practice. The chest will be open but pericardium left intact. Cardiac hemodynamics (PA wedge pressure, PAWP; PA pressure, PAP, right atrial pressure, RAP) will be measured using PA catheter already in place at rest, and then during conditions of increased cardiac preload, induced by passive leg elevation and saline bolus (300 ml administered over 1-2 minutes).

The surgical team will then perform anterior pericardiotomy, with removal of pericardial restraint similar to our percutaneous approach but using currently-available surgical tools. This will not be a complete pericardiectomy but rather a limited anterior incision to gain access to the heart for surgical exposure (standard care).

The surgical team will then repeat hemodynamic assessments at rest and with acute volume loading (leg raise + saline) in exactly the same manner as with the pericardium intact. Our hypothesis is that as compared to pericardium intact, the increase in PAWP with volume loading will be reduced following opening of the pericardium.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Anterior pericardiotomyProcedure or surgery

    The surgical team will perform anterior pericardiotomy. This will not be a complete pericardiectomy but rather a limited anterior incision to gain access to the heart for surgical exposure.

  • SalineDrug

    During the measurement of cardiac hemodynamic tests, a saline bolus of 300 ml will be administered over 1-2 minutes.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Pulmonary Artery Wedge Pressure (PAWP)

    Patients will undergo induction with general anesthesia, and at baseline the chest will be open, but pericardium left intact. Cardiac hemodynamics will be measured using the Pulmonary Artery Catheter already in place. The surgical team will then perform anterior pericardiotomy, with removal of pericardial restraint, and cardiac hemodynamics will be measured again.

    Measured: Baseline, approximately 1 hour

Secondary outcomes (2)
  1. Change in Pulmonary Artery Pressure (PAP)

    Patients will undergo induction with general anesthesia, and at baseline the chest will be open, but pericardium left intact. Cardiac hemodynamics will be measured using the Pulmonary Artery Catheter already in place. The surgical team will then perform anterior pericardiotomy, with removal of pericardial restraint, and cardiac hemodynamics will be measured again.

    Measured: Baseline, approximately 1 hour

  2. Change in Right Arterial Pressure (RAP)

    Patients will undergo induction with general anesthesia, and at baseline the chest will be open, but pericardium left intact. Cardiac hemodynamics will be measured using the Pulmonary Artery Catheter already in place. The surgical team will then perform anterior pericardiotomy, with removal of pericardial restraint, and cardiac hemodynamics will be measured again.

    Measured: Baseline, approximately 1 hour

Questions about this trial

What is this clinical trial studying?

A study testing Anterior pericardiotomy and Saline in people with Heart Failure, run by Mayo Clinic at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 May 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Pulmonary Artery Wedge Pressure (PAWP) (time frame: Baseline, approximately 1 hour). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 May 2019.
